One of my first projects. An Arduino Ohmmeter.
http://www.opensketches.org/arduino-ohmmeter/
Measures the resistor value and displays it on a LCD Display.
I really like it, and I have a suggestion: you could implement an automatic range finder. You only need several resistors for the potential divider. Maybe its possible to drive a CMOS4066 to select the right resistor.
Sorry for my bad English...
Thats a good suggestion. The more the two resistors have the same value, the exacter is the result.
Hi,
May I know what range and sensitivity can I expect from that setup?
Thank you.
Can't find the sketch. My computer says the webpage does not exist. Help?
